We present the unusual case of a 59-year-old female who pre-sented with right-sided retro-orbital pressure and rhinorrhea. Radiographic imaging revealed a mass centered in the right superior nasal cavity with extension through the cribriform plate into the right more than the left subfrontal region. Biopsy confirmed the diagnosis of a sinonasal schwannoma, which was resected via nasal endoscopic surgery and ethmoidectomy. These tumors, albeit rare, should be considered in the differential diagnosis for patients presenting with a para-nasal sinus mass to ensure inclusion of this benign lesion and avoid unnecessary aggressive in-tervention.展开更多
文摘Sinonasal schwannomas are rare, benign and slow-growing peripheral nerve sheath tumors without age, race, or gender predilection. We present the unusual case of a 59-year-old female who pre-sented with right-sided retro-orbital pressure and rhinorrhea. Radiographic imaging revealed a mass centered in the right superior nasal cavity with extension through the cribriform plate into the right more than the left subfrontal region. Biopsy confirmed the diagnosis of a sinonasal schwannoma, which was resected via nasal endoscopic surgery and ethmoidectomy. These tumors, albeit rare, should be considered in the differential diagnosis for patients presenting with a para-nasal sinus mass to ensure inclusion of this benign lesion and avoid unnecessary aggressive in-tervention.
